Abstract

Se describen composiciones y métodos para la recuperación de petróleo usando un sistema de polímero alcalino sin surfactante en agua dura o salmuera dura. La formulación incluye, además, un agente quelante, un agente alcalino (que puede ser el mismo que el agente quelante), y un co-solvente. Las formulaciones, tal como se describen aquí, son capaces de formar un surfactante in-situ, resultante en microemulsiones del tipo Winsor III de baja tensión interfacial.Compositions and methods for oil recovery using an alkaline polymer system without surfactant in hard water or hard brine are described. The formulation also includes a chelating agent, an alkaline agent (which may be the same as the chelating agent), and a co-solvent. The formulations, as described herein, are capable of forming an in-situ surfactant, resulting in microemulsions of the Winsor III type of low interfacial tension.
